     ISO/IEC 9899:2018 (ISO C17), and POSIX.1-2017.  Within 30112 we have the
     definition of a standard i18n FDCC-set, which for LC_MONETARY has the
     following default values:
	int_curr_symbol		""
	currency_symbol		""
	mon_decimal_point	"<U002C>" i.e. ","
	mon_thousand_sep	""
	mon_grouping		"\177" i.e. CHAR_MAX
	positive_sign		""
	negative_sign		"<U002E>" i.e. "."
	int_frac_digits		-1
	frac_digits		-1
	p_cs_precedes		-1
	p_sep_by_space		-1
	n_cs_precedes		-1
	n_sep_by_space		-1
	p_sign_posn		-1
	n_sign_posn		-1
    Under 30112 a keyword that is not provided implies an empty string ""
    for string values or a -1 for integer values, and indicates the value
    is unspecified with no default implied.  No errors are considered.
    The exception is mon_grouping which is a string with a terminating
    CHAR_MAX.
    For POSIX Issue 7 we have:
    https://pubs.opengroup.org/onlinepubs/9699919799/basedefs/V1_chap07.html
    and again values not provided default to "" or -1, and indicate the value
    is not available to the locale.  The exception is mon_grouping which is
    a string with a terminating CHAR_MAX.  For the POSIX locale the values of
    LC_MONETARY should be:
	int_curr_symbol		""
	currency_symbol		""
	mon_decimal_point	""
	mon_thousands_sep	""
	mon_grouping		"\177" i.e. CHAR_MAX 
	positive_sign		""
	negative_sign		""
	int_frac_digits		-1
	frac_digits		-1
	p_cs_precedes		-1
	p_sep_by_space		-1
	n_cs_precedes		-1
	n_sep_by_space		-1
	p_sign_posn		-1
	n_sign_posn		-1
	int_p_cs_precedes	-1
	int_p_sep_by_space	-1
	int_n_cs_precedes	-1
	int_n_sep_by_space	-1
	int_p_sign_posn		-1
	int_n_sign_posn		-1
    Like with 30112, POSIX also considers no error if the keywords are
    missing, only that if the cateory as a whole is missing the referencing
    of the category results in unspecified behaviour.
    For ISO C17 there is no default value provided, but the localeconv
    specification in 7.11.2.1 admits that members of char * type may point
    to "" to indicate a value is not available or is of length zero.
    The exception is decimal_point (not mon_decimal_point) which must be a
    defined non-empty string.  The values of char, which are generally
    mapped to integer values in 30112 and POSIX, must be non-negative
    numbers that map to CHAR_MAX when a value is not available in the
    locale.
    In ISO C17 for the "C" locale all values are empty strings "", or
    CHAR_MAX, with the exception of decimal_point which is "." (defined
    in LC_NUMERIC).  ISO C17 makes no exception for mon_grouping like
    30112 and POSIX, but a value of "" is functionally equivalent to
    "\177" since neither defines a grouping (though the latter terminates
    the grouping).

    Lastly, we must consider the legacy C/POSIX locale that implemented
    as a builtin in glibc and wether a default value mapping to the
    C/POSIX locale may benefit the user from a compatibility perspective.

    Thus given 30112, POSIX, ISO C, and the builtin C/POSIX locale we
    need to pick appropriate defaults below.   */

  /* The members of LC_MONETARY are handled in the order of their definition
     in locale/categories.def.  Please keep them in that order.  */

     earlier when a default category is created (completely missing category).
     This missing field warning is glibc-specific since no standard requires
     this warning, but we consider it valuable to print a warning for all
     missing fields in the category.  */
